Subject: Bug: \adjustspacing=1 does not disable expansion
Date: Thu, 5 Dec 2019 10:04:19 +1300 [thread overview]
Message-ID: <a42ef879-0836-de84-b71b-f45457f649b5@gmail.com> (raw)
Dear devs,
The \adjustspacing register is described in the LuaTeX manual as
follows:
When \adjustspacing has value 2, hz optimization will be applied to glyphs and kerns. When
the value is 3, only glyphs will be treated. A value smaller than 2 disables this feature.
However, setting \adjustspacing=1 will only disable shrink but not
stretch. Please find a minimal example example, where I have used
exaggerated values for shrink and stretch to emphasize the issue. It
can be reproduced with both mtxrun --script plain and luatex with
luaotfload.sty.
I have already checked linebreak.c but add_to_widths looks innocuous and
properly checks the adjust_spacing parameter.
Cheers, Henri
